The novel capacitor for inhibiting the power supply electromagnetic interference comprises a shell and a capacitor part in the shell, wherein epoxy resin is filled between the capacitor and the shell; the shell is provided with a lead wire; the capacitor part comprises X type capacitors and Y type capacitors; and two Y type capacitors are connected in series and then connected with one X type capacitor in parallel. The novel capacitor has high interference resistance and an integrative reasonable design, is convenient to mount and improves the reliability; and the volume of the capacitor is reduced, material consumption is reduced, manpower is saved, and the effect of the capacity is obvious.
Description
Technical field
The present invention relates to a kind of capacitor, relate in particular to a kind of novel inhibition power supply electromagnetic interference capacitor.
Background technology
Traditional power supply adopts X class electric capacity and Y class electric capacity with suppressing the electromagnetic interference capacitor, and major part has adopted split type wire laying mode in the line, has wasted bigger printed substrate resource, has brought obstruction also for the microminiaturization of entire product.Many capacitor producers bundle plastic packaging then with these two types; Form a bulk container, the capacitor that separates is integrated in this combination, and assembling process needs the manual work of labor; The volume of finished product does not also reduce, and the product summation of the preceding separate elements of assembling also wants big.In fact volume, minimizing consumable material and the saving manpower of this simple assembling to reducing capacitor, the effect that is risen is also not obvious.
Summary of the invention
The invention discloses a kind of novel inhibition power supply electromagnetic interference capacitor; Described novel inhibition power supply electromagnetic interference capacitor comprises the capacitor element in shell and the shell.Be perfused with epoxy resin between described capacitor element and the described shell body, described shell body is provided with lead-in wire; Described capacitor element comprises X class capacitor and Y class capacitor.
Described X class capacitor is the metal film winding capacitance that metal-plated membrane is closely reeled and formed on the plastic film; Described Y class capacitor is a ceramic condenser; After being in series, described Y class capacitor is in parallel with X class capacitor.The one side central authorities of described X class electric capacity scribble conductive layer and are connected with central electrode lead-in wire, and scribbling two relative one sides of conductive layer with central authorities has conductive layer near the part at two ends with adjacent surface.
Be provided with the central electrode lead-in wire between the described Y class capacitor, stretch out shell through wire holder.X class capacitor two ends are provided with contact conductor, stretch out shell through wire holder.
The shell of the novel inhibition power supply of the present invention electromagnetic interference capacitor is set to cuboid.
Described X class capacitor is the metal film winding capacitance that metal-plated membrane is closely reeled and formed on the plastic film, and the metal film that is coated with on the plastic film of described electric capacity is the aluminium film.
Described shell is plastic box, adhesive tape layer or epoxy resin application layer.
The present invention composes in parallel with an X class capacitor after two Y class capacitors in series are arranged, and has good antijamming capability, and incorporate appropriate design is convenient to install, and has improved reliability; Reduce capacitor volume, reduce consumable material and save manpower, play that the good results are evident.
